METHOD- OF OIRNAMENTING METAL PLATEIS FOR JEWELRY.

' SPECIFICATION forming part of'Letters Patent No. 30 2,036, dated July15, 1884.

Application filed May 14, 1884. (No model.)

Be it known that I,-'JAMEs RoTHsoHILD, a citizen of the United States,residing at Newark, in the county of Essex and Stateof New Jersey, haveinvented a new and useful Improvement in Metal Ornamentation, of whichthe following is a specification,

My invention relates to a method and means for ornamenting metal platesfor jewelry-stock and for the finished production as a new arti'cle ofmanufacture.

" dented in simulation of engraved lines, said lines of each sectionaldivision extending upwardfrom the base. By this means I produce anornamental metal plate having a series of embossed figures, thepolygonal sides of which present divers and diverse angles, whichreflect and refract light at various incidences, the effect being togive to said metal and to articles of jewelry made therefrom theappearance of a series of gem-settings prismatic in character. Thiseffect is heightened and in creased when the plate surface ismulticolored. According to the present fashion, there is a great demandin the manufacture of jewelry for stock plate that has a party-coloredor embossed surface, or both combined. The party-coloring is produced bya variety of treatments, not herein necessary to describe, as myinvention can be applied to any description of multicolored plate thesurface of which is normally smooth and unbroken, or to a plate with'asingle surface color. Therefore -I will observe that I do. not inpractice confine myself to plates either of a single-color or of party Tcolor surface, the main object and purpose of my invention and the gistthereof being to upraise certain sectionally-divided portions of metalplates and to ornament in simulation of engraved lines the sides of eachraised section, as and for the purpose herein described, andspecifically pointed out in the claims.

Referring to the accompanying drawings, in which similar letters ofreference indicate like parts on each figure, Figure l'represents ametal plate ornamented according to my invention. Figs. 2'and 3 are likeviews showin'g parts of the plate left plain. Fig. 4 represents thebezel of a locket or brooch embody.-

ing my invention.

A is a metal plate; a, the plain surface thereof; a, raised sectionaldivisions thereof, a lines on the raised sides of the divisionalsections. When the figure is a cone or of any shape in which the basedoes not present a11- gular sides, it will be necessary to arbitrarilydivide the line of-the base into sections, on each of whichlinesparallel-andextendingup ward from the base-line are to be placed,the parallel lines in each section to be in a different direction fromthose in the adjoining secsive elevations must have its sides indentedor impressed in imitation of engraved lines. I This form is plainlyillustrated on Fig. 3at B. It is not necessarythat the whole plane ofthe metal plate shall be covered with the desired ornamentation. Partsthereof may be left smooth and plain, as illustrated in Figs. 2 and 3.This plain surface may be further ornamented in a variety of ways-as,for instance, etching, chasing, engraving-and will provide a space forplacing initials, mottoes, monograms, or the like thereonas, forinstance, if the bezel C, Fig. 4, were stamped or embossed up and thecentral portion, 0', to consist of a'plain plate. So, too, may suchplain surface be enameled or colored, in whole or in part, as taste orconvenience may dictate. It will thus be seen. that Iprovide for anindefinite variety of ornamentation by my improvement and by combinationwith other well-known devices.

The process by means of which I produce the ornamented plates, ashereinbefore demale dies, the main pattern to be produced being inprojectioi1 on the male die-roller,

the female die-roller being provided with cor responding depressions;but in addition thereto, upon the sides of each depression upon thefemale die, are a series of indented lines extending from the base ofeach side, and as the metal passes between the rollers the divisionalsections are not only forced up or embossed by means of the male die,but the opposite side surface of each projection is imprinted by thesaid lineal indentations in exact imitation of line engraving. Ofcourse, instead of using die-faced rollers, the sectional divisions,orna mcnted as described, maybe formed on the metal by striking it upbetween male and fe male hubs or dies.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. The within-described method of producing ornamental metal work of thecharacter specified,which consists of the following steps: first,preparing a male die with divisional sectional projections. the centralpoint of each of said projections being higher than any other portionthereof, then preparing a female die with depressions coincident withthe projections of the male die, then engraving 01' otherwise indentingupon the sides of each depression of the female die lines extendingupward from the base of such depression, then placing a metal platebetween the male and female die, and then subjecting said plate topressure, as and for the purpose intended, substantially as described. 4

2. As a new article of manufacture, an ornamental plate for jewelry-stock, having upon its surface a series of divisional sectionalprojections, each of which projections being higl1- est at its centralpoint, in combination with lineal indentations upon the sides of eachprojection extending from the base upward, as and for the purposeintended, substantially as described.

3. As a new article of manufacture, an article of jewelry having anornamental surface composed of a series of divisional sections,thecenter of each of said sections being the more elevated point thereof,the deflecting side of each of said sectional elevations being suppliedwith lineal impressions extending from the base upward, substantially asdescribed.

4. As a new article of manufacture, a plate for ewelry-stock, havingportions of the surface thereof smooth and plain and other por tionsprovided with sectional divisional projections,thc center of each ofsaid projections being higher than any other portion thereof, thedeflecting sides of each projection being supplied with linealimpressions extending from the base upward, substantially as described.

5. The combination, with the pariy-colored surface of a metal plate forjcwelcrs stock, of divisional sectional elevations having their highestpoint at their centers, and their dcflected sides provided withimpressions extending in right lines upward from their bases,substantially as described.
